Extraction of Nicotine from Tobacco Leaves used for Animal Cleansing
Abstract: Nicotine is addictive. An average cigarette yields about 2 mg of absorbed nicotine, and in lesser doses of that order, the substance acts as a stimulant in mammals, while high amounts (50-100 mg) can be harmful. This stimulant effect is a contributing factor to the addictive properties of tobacco smoking. Nicotine’s addictive nature includes psychoactive effects, drug-reinforced behavior, compulsive use, and relapse after abstinence, physical dependence and tolerance. Nicotine can …
